Review request for mesos, Gilbert Song, Jie Yu, Joseph Wu, and Qian Zhang.
Bugs: MESOS-6052
https://issues.apache.org/jira/browse/MESOS-6052
Repository: mesos
Description
-------
In case /etc/hosts and /etc/hostname files are not present in the host
filesystem, we were ignoring these files and assuming that they would
not be required by the executor when it is launched in a new network
namespace. This assumption is incorrect, since the executor needs
/etc/hosts in the new network namespace to resolve its hostname.
Hence, we are explicitly creating these files in the host file system
in case they are not present, so that containers /etc/hosts and
/etc/hostname can be mounted on these mount points. This solves the
problem in distributions such as CoreOS that don't have /etc/hosts in
their host filesystem.

Testing (updated)
-------
make check
Also, build an open DC/OS image with this patch to run on CoreOS and tried
launch a unified containerizer through Marathon using dcos-cli to test this
patch on CoreOS.
